This is the part of the atom that has a positive charge and identifies that atom.
What is the proton?
100
This is a combining of substances that can be separated by physical means.
What is a mixture?
100
This is a property of a substance that describes how the substance reacts with something else to form a new substance.
What is a chemical property?
100
This coefficient must be added to make this equation balanced: H2O2 ----> H + O2 (All numbers are subscripts)
What is a 2 in front of the H?
100
This is how many valence electrons the element Fluorine has.
What is 7?
200
This is the part of the Periodic Table that tells you how many protons and electrons are in a neutral atom.
What is the atomic number?
200
This is a combination of substances that are shown with a chemical formula.
What is a compound?
200
This is a change that does not change what the substance is.
What is a physical change?
200
The addition of these two coefficient would balance the following equation: H2O2 ----> H2O + O2 (all numbers are subscripts)
What is a 2 in front of H2O2 and a 2 in front of H2o?
200
This is the amount of electrons that Magnesium wishes to get rid of?
What is 2?
300
These are the electrons on the outermost energy level and that determine the type of bonds that an atom will make.
What are the valence electrons?
300
This type of mixture contains an even amount of each substance in every sample.
What is a homogeneous mixture?
300
An example of this type of property is pH.
What is a chemical property?
300
These coefficients must be added to balance this equation: N2 + H2 ----> NH3 (all numbers are subscripts)
What is a 3 in front of H2 and a 2 in front of NH3?
300
This is the type of bond that Sodium (Na) and Chlorine (Cl) make.
What is an ionic bond?
400
This is a type of atom where the atomic mass has changed, thus changing the amount of neutrons.
What is an isotope?
400

What is 6 Carbon, 13 Hydrogen and 11 Oxygen?
400
An example of this type of change is when clay is molded to form a ball.
What is a physical change?
400
These are the two sides of a chemical equation.
What are the reactants and the products?
400
This is the type and number of bonds that two Oxygen atoms would make.
What is a double covalent bond?

500
Color change and the production of bubbles are evidence of this kind of change.
What is a chemical change?
500
The reason that equations must be equal on both sides.
What is that matter is not created or destroyed in a chemical reaction?
